less

NAME

SYNOPSIS

DESCRIPTION

This is a user-pragma. If you're very lucky some code you're using
will know that you asked for less CPU usage or ram or fat or... we
just can't know. Consult your documentation on everything you're
currently using.

FOR MODULE AUTHORS

less has been in the core as a "joke" module for ages now and it
hasn't had any real way to communicating any information to
anything. Thanks to Nicholas Clark we have user pragmas (see
perlpragma) and now less
can do something.

You can probably expect your users to be able to guess that they can
request less CPU or memory or just "less" overall.

If the user didn't specify anything, it's interpreted as having used
the please
tag. It's up to you to make this useful.

BOOLEAN = less->of(FEATURE)

The class method less->of(NAME)
returns a boolean to tell you
whether your user requested less of something.

if (less->of('CPU')){

...

}

elsif (less->of('memory')){

}

FEATURES = less->of()

If you don't ask for any feature, you get the list of features that
the user requested you to be nice to. This has the nice side effect
that if you don't respect anything in particular then you can just ask
for it and use it like a boolean.
